Configuring Firewall Systems Home internet and computer networks are often exposed to an increasing number of security threats. Examples of such threats may include virus attacks, malware intrusion, denial of service attacks, as well as unauthorized access incidences such as hacking. Networks are group of computer systems that are interconnected either with the use of wireless technologies to enable sharing of resources such as files or sharing of services such as internet connectivity. The nodes within a home network may include computers, printers, connecting devices, as well as components utilized for sending and receiving data collected by other devices on the network. Firewalls can safeguard home network systems by acting as collection of components that are positioned between the inner and outer network in order to protect it from external security threats. Only authorized traffic must pass through a firewall. One type of firewall that is ideal for home network is packet filtering firewall. Network layer firewalls, also referred to as packet filtering, enables only certain types of packets to pass through the firewall. Every packet is compared to a collection of rules that have been configured for the network interface. Rules can be put in place for both incoming and outgoing packets. The norms of packet filtering are founded on information in the transport protocol header and the IP header. The packet filters can act as personal home firewall to control network traffic to and from a specific personal computer. The firewall works by permitting or denying communications on the basis of security policies that have been established. The personal firewall can be placed on the application layers of the firewall. The firewall runs on a workstation to block undesired traffic, usually from the network system. It can work to complement the work of conventional firewall by screening the types of data that a single host can accept. .

Home internet and computer networks are often exposed to
an increasing number of security threats. Examples of such
threats may include virus attacks, malware intrusion, denial of
service attacks, as well as unauthorized access incidences such
as hacking. Networks are group of computer systems that are
interconnected either with the use of wireless technologies to
enable sharing of resources such as files or sharing of services
such as internet connectivity. The nodes within a home network
may include computers, printers, connecting devices, as well as
components utilized for sending and receiving data collected by
other devices on the network. Firewalls can safeguard home
network systems by acting as collection of components that are
positioned between the inner and outer network in order to
protect it from external security threats. Only authorized traffic
must pass through a firewall. One type of firewall that is ideal
for home network is packet filtering firewall.
